I have had the Flex since Christmas and have recorded my Sleep History every day sine.

It looks good to see ones sleep/sleepless hours but I have not found any real use for this part of the program

Someone else may have an answer or Fitbit may help.

I've kept track of my sleep numbers for a few weeks, with a brief log of daily activity to try to determine if anything I do influences my sleep.  My nightly effiency on the sensative scale ranges from from 56% to 82%, on the other scale: 90% to 100%.  I can't find any correlation between my daily habits and sleep effiency.  Nor do I know if those numbers are good or bad.  Anyone else have thoughts?

I've found it very helpful in keeping track of my moods. I'm bipolar and sleep is one of the most influential aspect of bp. It's also allowed me to see which medications have a positive influence and which don't, making it easier to find just the right medication for me to use. 

But unless you had a specific goal in tracking your sleep it might be cool and that's all.

Golden makes a good point.  I have use the data for similar purposes, such as seeing patterns between stress, certain activities, and the menstrual cycle and sleep disturbances.  For instance, looking at the big picture of sleep data, I saw that I was more restless on days I had to spend lots of time driving for work.  Armed with this info, I now take steps to relax, such as meditating and stretching before bed, to sleep better at those times.

By looking at my pattern of sleep over a couple of weeks I noticed if I ate close to bedtime I fell asleep quickly, but remained restless for an hour or more.  No food for a few hours resulted in me falling into more rested sleep  (an extra hour of quality sleep a night is a full nights sleep a week!).

I have used it to see my sleep patterns, when I am restless and awake throughout the night. It also opened my eyes to how little sleep I get each night usually 6 hours.
